IMPROVEMENT IN WASHING-MACHINES.

Specification forming part of Letters Patent No. 178,879, dated J une20, 1876; application filed August 30, 1875.

To all whom it may concern:

Be it known that I, EDWARD J. RoBtNsoN, of Schenectady, and State of NewYork, have invented a new and useful Improvement in Washing Machines, ofwhich the following is a specification:

The object of this invention is to furnish an improved machine forwashing clothes; and consists in the construction, arrangement, andcombination of parts hereinafter described.

Figure 1 represents a vertical longitudinal section of the machine. Fig.2 is a sectional end view.

Similar letters indicate corresponding parts in the specification anddrawing.

A is a water-tight box, of suitable form and size, which contains therevolving cylinder B. This cylinder is composed of two endsor heads, 0O, and the staves D, having open spaces E between. Three (more or less)of the staves are connected together and form a door, which slidesbeneath the bands on the heads of the cylinder, and is removed forgiving access to the-interior, for introducing the clothes to be Washed.The cylinder is supported on short journals F by the crotch box-pieces GG, which pieces are attached to the ends of the box A. The cylinder isrevolved by means of the crank H and the gear-wheel I and pinion J, thegearwheel I being attached to one of the heads of the cylinder, andhaving on it one of the short journals 1*, the other short journal beingon a plate which is screwed to the other head. The pinion J is on theend of the shaft K, which is supported on the top of the box A in thebearing-boxes L L, in which boxes the shaft slides. M is the top orcover of the box A,

which is removable, and is slotted or notched around the pinion J. Thecylinder is removed from the box A by taking off the nut N and thewasher Ofrom the shaft K, and removing the pinion and slipping back theshaft. 111- side the cylinder is a roller, P, whichrevolves freely asthe cylinder is-revolved, and presses upon the clothes. This roller maybe of any suitable length and diameter.

The operation is as follows: The cover M is first removed and asufficient quantity of water or suds is placed in the box. The clothesare then put in the cylinder and the cover is replaced. The cylinder isnow revolved by turning the crank, and the clothes are washed withoutrubbing and wearing them, as in ordinary machine or by hand washing.

This machine is similar in many respects to the machine described in mypatent dated June 1, 1875. In that machine the construction of thejournals and boxes requires nice workmanship and, skilled labor, whichenhanced the cost and rendered the machines unremunerative. With thepresent machine this objection is obviated.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The nut'N, washer O, and sliding shaft K, in combination with thegear-wheel or pinion J in a washing-machine,'as and for the purposedescribed.
